I know it's the doctor who should help you with this but I also understand we have to take some responsibilities for our own health within reason. I wanted to respond to your question because I went through the same thing, not only with Sertraline but several other antidepressants, also I'm a long time user of Ativan too. I had to come to the conclusion that these antidepressants do not agree with my system and often gave me worse feelings that what I already had to cope with. I still use Ativan for anxiety and it definitely helped me stop the antidepressant, the withdrawal is easier to deal with and I hope it can do the same for you, also perhaps you need to ask your doctor what dosage is best for you to go with or they might have another method for you to try, good luck with this and know that you're not alone.
